NOZZLE OF HOSE-PIPES.

Speccaton of Letters Patent No. 26,994, dated January 31, 1860.

To all ywhom 'it may concern:

Be it known that I, NIKoLAUs IIoTz, of Trenton, in the county oflWIercer and State of New Jersey, have invented a new and usefulImprovement in the Construction of the Nozzles of Hose-Pipes, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings'7 which make part of this specifica--tion, andin which- Figure l represents a longitudinal, axial, sectionthrough a portion of a hose-pipe and nozzle embracing my improvement.Fig. 2 represents a view of the nozzle and coupling, as seen from above(with the former in section) showing more especially the relativeposition of the parts when the valve of the nozzle is opened to itsgreatest extent. Fig. 4 represents a similar view of the same, with thevalve partially closed. Fig. 3 rep resents a similar view of the samewith the valve closed still more than in the preceding figure; and Fig.5 represents a similar view of the same with the valve entirely closed.

Owing to the general introduction of abundant supplies of fresh waterinto large cities their inhabitants are enabled to make free use of itfor the purposes of cleaning, laying the dust, &c. but the employment otthe common hose pipe with an ordinary stopcock in the nozzle (to enablethe person using it to shut otf the iiow at will) is attended with muchinconvenience and expense of construction. To obviate the objections towhich this construction of nozzle is subject I have invented a. newarticle of manufacture, constituting an improved hose-nozzle, cheap andsimple in its construction and of great durability; and my inventionconsists in so constructing the nozzle for hose, whether used forextinguishing tires or for cleansing purposes, as that while the commonstopcock is entirely dispensed with, the flow of the water may readilybe regulated at the pleasure of those to whom the use of such hose maybe necessary or convenient. To accomplish these objects I arrange aperforated diaphragm, disk, or plate, ot elastic material, within thedischarge-pipe in such manner that it shall work in contact with anauxiliary diaphragm, disk, or plate, corre spondingly perforated andattached to the nozzle of said pipe, which nozzle is so arranged as torevolve on the pipe to open and close its valve.

To enable persons skilled in the art to make and use my improved nozzleI will now proceed to describe its construction and mode of operation.

In the accompanying drawings the pipe (a) and nozzle (b) are representedas con nected by the nut or coupling (c). The nozzle (o) has a rim orange (d) on one end to hold it within a corresponding rim (c) on the nut(0); by which means the nozzle is left free to turn within the couplingbut cannot escape therefrom. A plate (f), which I call the nozzle-plate,extends across the end of the. nozzle, and has openings (g) through itin the form of sectors of a circle, for the `passage ofl the water. Thepipe (a) has a male screw on one end which takes' into a female screw inthe coupling A plate (71,), which I call the pipe-plate, similar to theone already described, except that it is made of leather, gutta-percha,india-rubber, or some other elastic material is placed against the endof the nozzle (b), within the coupling and the pipe (a) screwed in;thereby forcing the plates (/L, and into close contact, and forming atight joint. This plate (h), after being so placed in the pipe that itsopenings occupy the proper relative position to those of thenozzle-plate (f), is prevented from turning by a projection on the innerside of the pipe.

The operation of the nozzle is a follows. Suppose the plates (f, h) tobe in the position represented in Fig. 2, of the drawings,

that is with their apertures opened to their greatest capacity. Now if adiminution in the flow of the liquid is desired, it is only necessary tograsp the pipe with one hand and turn the nozzle on its axis with theother, by a pivotal movement, and the plates will gradually slide overeach other until they assume the position shown in Fig. 4:, when the lowwill be diminished; and by continuing this movement until the partsassume` the position shown in Fig. 5, the flow will be entirely checked.

A suitable stop or catch (i) on the nozzle, traverses a notch in thecoupling, and prevents the nozzle from being turned so far as to reopenthe discharge apertures.

The nozzle-plate being made of metal is consequently very durable, andmay if preferred be cast in one piece with the nozzle. The pipe-plate ismade of some elastic material (as above mentioned) and is held closely'against the nozzle-plate by the hydrostatic pressure of the water, aswell as by the screw, by which means any tendency to leakage iseii'ectually prevented. If however the plate should become worn out orde- :Eective it may readily be removed by unscrewing the coupling, and anew plate substituted. By this method of construction I am eanbled tosecure a hose-nozzle which is cheap and simple in construction, durableand eiicient in operation, and easily adjusted or repaired when out oforder.

It is obvious that my invention is a decided improvement over thosenozzles which though somewhat similar to mine in some respects, yet havethe cock operated by an independent handle, which is always catching insomething and impeding the handling of the pipe, besides being much morecomplex and costly in construction.

I do not claim broadly a valve composed of two perforated disks orplates sliding over each other, as I am aware that this is a Well knowndevice, but I claim as a new article of Ymanufacture- A hose-nozzleconstructed as herein set forth.

In testimony whereof I have hereuntoisub-l scribed myname.
